The appeal, which launched in November, is an opportunity for readers to offer their support by making a donation to the three deserving causes. In addition to the wonderful support offered by The Telegraph readers, Roald Dahl's Marvellous Children's Charity's celebrity ambassadors have been sharing their stories, demonstrating why they are proud to support the charity.

Liccy Dahl, Roald Dahl's widow who started the charity twenty-five years ago says "Roald knew from tragic experience how crucial nurses are." She says that all Roald Dahl nurses are highly valued and highly qualified, "They are there from the moment of diagnosis, an extremely frightening and lonely time for both the child and the parents, a moment I have experienced as a parent myself. They are there to explain this diagnosis and to help them with the care and support that will be needed in the future. They will hold their hands, listen and bring comfort." Read more.

Claudia Winkleman, one of the charity's celebrity ambassadors shares Liccy's view, she says, "They look after the underdogs of the medical world, whether it's children with conditions so rare they can't even get a diagnosis, or with illnesses that rarely get funding. I'm proud to say I support the work of the Roald Dahl nurses, the quiet heroes who give so much to help and hope to thousands of families who are trying so hard to cope with their child's condition. I think what they do is, quite simply, marvellous."

Celebrity ambassador Julie Walters has also shared her view on how important nurses are to families caring for a seriously ill child and why more money is needed to help fund additional nursing posts. She says, "Illness is so scary and so many people suffer from little-known diseases that people don't particularly hear about...they need proper support from these fabulous nurses." Read more.
